SANDPAPEBING AND BUIIIING MACHINE.

. Application fled Kay 8, 1996. Serial No. 106,441.

My present invention pertains to sandpapering and bufiing machines andit eontemplates the, provision of a simple, inexpensive and readilyportable device through the medium of which automobiles or other highlypolished surfaces may be easily and quickly polished, sand papered andotherwise buifed with but a slight amount of effort on the part of theoperator. The invention further contemplates a portable sanding andbufling machine for the purpose set forth that is adapted for beingreadily interchangeable with respect to the bufiing element employed. 4

The invention in all of its details will be fully understood from thefollowing des er1ption and claim when the same are read in connectionwith the drawings accompanying and forming .part of this specification,in which Figure 1 is .a side elevation of my novel device.

Figure 2 is an inverted plan view thereof. Figure 3 is a sectionaliviewof'Figure 1. 35 Figure 4 is a View taken in the plan indicated by theline H of. Figure 1 and looking in the direction of the'arrows.

Figure 5 is a side elevation of a sand paperingelement that may be.substituted for the bufling element. 7

Similar numerals of reference designate corresponding parts in all theviews of the drawings.

My novel device comprises a casing that is indicated asa whole by. 1 andthe said casing is provided with the curved guar portions 2 and anedge'l'ower portion 3 and a'rran ed in the edge portion 3 is an indentedsurfaced at one end and an indente 4 surface 5. at the opposite end ofthe casing, the indented-portion 5'be1ng slightly larger than theportion 4, for a purpose hereinafter specified.

Secured to the forward portion of the cas- 6 that is heldto the casingby means 0 the bolts 7. This strap rests in the indented ortion 4 of theedge 3 and not only deplen s slightly below the edge 3 but is firmly eldagainst the casing and against side-wise movement by the abutting edgesof the indented surface 4 of the edge 3'. Similarly secured at the rearportion of the casingas referred to in this specification is a bearingstrap 8 that is secured to the casing by means of a bolt 9 and thisstrap rests between the abutting edges dto d tuation of the plished.'

of the indented ortion 5 of the edge portion 3 and depen s from the edge3 approximately the same length or distance as the strap 6. These strapsare similar in construction except that the strap 8 is adjustable whichis accomplished by providing a semicircular slot 11 and adjusting bolt10. The purpose of this adjustment 18 to take up-wear and the furtherpurpose will be ap-- preciated by reference to the later description ofthe device.

Secured in the bearing strap, 6 is a shaft '12 and mounted on this shaftis a roller 13 whilesecured in the bearing strap 8 is a shaft 14 onwhich is arranged the spool-or drum 15. The roller 13 is in fact a drumsimilar to the drum 15.

Adapted to rotate through the medium of the rotatable drums 13 and 15 isan endless belt 16 and in Figure 1 I have illustrated the belt 16 asprovided with sheep wool or other high-grade bufiing material 17, but atthis point I would distinctly have it understood that the endless beltmay be provided with any bufling material, such for instance as sandpaper, emery or the like. The endless belt 17 is readily adjustable bymeans of the adjusting boltand slot 10 and 11.

Mounted on and preferabl bolted to casing 1 is a light motor 18 t at isprovided with a V type pulley 19 and adapted to rotate through means ofthe pulley 19 is a pulley belt 20 that in turn actuates a V type pulley21 fast on the shaft 12. Apparently rotation of the pulley 19 willimpart rotation the pulley 21 which in turn rotates the drum 19 therebyimpartin' movement to the belt 16 and the drum 15. n this manneraobufiing element is. accom- In order to assist in the easy handling ofthe device I have provided a-handle 22 that is adjustably mounted at 23on the casing 1.

Although I have deemed it unnecessary to illustrate nevertheless I wouldhave it understood that the drums 13 and 15 ma be .remov'ably arrangedin the casing 1 an vreleased .through means of a trigger from the casingso that removal of one 'bufiing element and replacement ofanother may beaccompliphe 'Any form of construction tilt-13x18 we 1 known in the artmaybe emplo ed for this purpose and I make no speei c c aim to thisarran emen "1 It must-lie borne in mind that the primary and salientfeature of my invention is distinctly novel sand the device and thoughvicefor use as a bufiin that the improvements I papering'. 1

When desired the belt 24 having the sand Eager surface 25 may besubstituted for the u g element 17.

palperin features of ave s own the demachine, I prefer e confined tosand earners walls of the machine; one of said straps being retainedsnuglyin one of the indentions and the other of which is ada ted to beadjusted with respect to the si e wall and'within the complementaryindentions, a slot formed in one of the straps to enga 'e adjustingmeans, shafts 'ournalled in t e lower ends of the straps, rums mountedon the shafts, a bufling element arranged on an endless belt; saidendless belt being actuated by the drums and means for actuating one ofthe shafts.

In testimony whereof I have hereunto set my hand. I
